Monthly Summaries

The month of January across Wyoming saw the average temperatures come in at above normal, with a couple of sites with below normal numbers. Precipitation for the month was mostly below normal, with just Casper and Lander above. Casper did see record snow of 6.8 inches on the 21st, and Lander had record liquid (melted snow) on the 5th. Both of these records are significant due to their long period of record. The early days of the month did see the coldest temperatures with the 1st and the 6th being the favorites. There was a front on the 3rd and 4th that brought some snow to the west, with Winter Weather Advisories issued. There were also strong winds for the south and east with this front. Buffalo hit 69 mph on the 4th, which is the highest speed for the month of all the sites. The 5th and 6th saw another system with snowiest and wettest days in the climate sites in central areas.

There were a series of small fronts crossing the state throughout the month, with a trace to a few inches of snow each time, mainly east of the divide. That snow did not hang around too long with most of them. A front on the 20th and 21st gave Casper a decent snow day, and one on the 27th dropped a few inches on Lander. The month of January ended on a high note…meaning it was a very windy day with High Winds across the state. Riverton and Worland had their highest gusts on the 31st. The temperatures also were above normal for the last week of January.
